ELEGTRiG-LIGHT-STA'ND ADJUSTER.

Application filed January 13; 1928. Serial No. 612,492.

To all whom it mag concern: c Be it known that we, ANTHONY 'Mn'YEns andHArRY SIMMONS, citizens of the United States, residing at New York, inthe county 6 and State of New York, have invented certain new and usefulImprovements in Elece tric-Light-Stand Adjusters, of which the followingis a-fu'll, clear, and exact specification, V 7 10 This inventionrelates to means for adjusting or securingielectric light stands orlamps to various .fixtures,; such. as tables, mantel shelves, windowsills, or bedsteads where most convenient to the user for read- 16 ing,sewing, etc; I

One object of the invention is to pro ,vide clamping means for thepurpose stated on the base of a stand lamp which may also be used in theordinary way on a table, or

20 the like, without bringing'said clamping means into play, and toarrange said clamp ing means in the base of the lamp so that it will notinterfere with the setting ofsaid stand on a level surface. At the sametime, said clamping means is adapted to be projected below the base ofthe lamp for securing the same to the edge of a table, or to otherfixtures, whenever desired.

Another object is to provide improved means for actuating said clampingmeans from above or outside the base of the lamp to which it isattached. Still another object is to provide a lamp of the characterdescribed with an adjustable socket member which may be turned to assumedifferent angles with respect to the stand, and may also be rotatedabout the vertical axis of said base so as to bring a lamp mountedinsaid socket into the position best suited for its use no matter how thebase is secured to a fixture by the clamping means. Other objects willappear as the description proceeds. c K v The invention will be firsthereinafter described in connectionwith the accompanying drawings, whichconstitute part of this specification, and then more specificallydefined in the claims at the end of the description. 50 In theaccompanying drawings, wherein similar reference characters are used todesignate corresponding parts throughout thefseveral views c Figure 1 isa side elevation, partly in vertical section, of a lamp or standconstructed substantially in accordance with this invention and adjustedor clamped to the edge of ashelf or other fixture. Q i

'Figure 2 is a bottom plan of the stand or lamp as shdWninFigure 1except that'the fixture is omitted and the clamping means folded intothe'cavity in the base of said stand. V

Figure '3 is a broken section on the line III-III of Figure 1 with theparts drawn to a larger scale to illustrate moreclearly the connectionbetween the clamp and its operating device, and Figure 4 is a detailedplan View ofa modified form'of operating device for the clamp whichmaybe used in place ofthat illustrated in the other views;

The lamp stand comprises ajbase 1- preferably of sheet metal formed witha recess 2 in its bottom, a tubular standard 3 rising from the center ofsaid base and preferably secured rigidly thereto by solder or the like,and a. socket, member 4 arranged at the upper end of the standard 3 andhinged at 5 u per, end of the rod 6 and the lamp socket 4 is placedunder sufficient tension by a bolt 7 to insure said socket remaining inany angular adjustment desired. Said socket 4t may be fitted with anelectric light bulb 8 V and a shade or reflector 9, as shown in Figures1 and 2, and a cord or wire cable 10 may lead to said socket through thetubular rod 6 and the base of the lamp.

The rod 6 and lamp socket 4: hinged thereto maybe rotated in thestandard 3 so as to swing the bulb into different positions about thebase, and in orderto retain said rod in its different adjustments orpositions when rotated in the standard,a coiled spring 11 is mountedaroundsaid rod within the standard, one end of said spring bearingagainst a collar 12 fixed on the rod and the other end of said springbearing against a washer 13 and tending to ress itinto frictionalcontact with the top of the base 1 within the lower end of the standard.Said spring bearing upon the collar 12 tends to raise the rod 6 and thuspresses a washer 1 1 on its lower end against the upper surface of thetop of the base. The washer l l is held on the lower end of the rod 6 byasuitable nut 15, or the like.

A radially projecting arm 16 is fixed to turn with the rod 6 and extendsinto the path of a stop 17 fixed to the base within its recess forlimiting the rotation of said rod to one revolution about the base, soas to prevent undue twisting of the wire cable or cord 10. Said arm 16may be secured between the washer 14 and nut 15 and have a portion 18bent down against one of the flat sides of the nut to insure the turningof said arm with the rod, as shown in Figures 1 and 2. The cable or cord10 may enter the base at any desired point, as through the eyelet 19 inthe side of said base.

A clamping jaw 20 is hinged at one end on a cross pin 21 in the recessof the base and is adapted to be folded into said recess so as not tointerfere with the base resting evenly upon a table or other levelsurface. A coiled spring 22 mounted on said pin 21 and having its endsbearing respectively against the base and clamping jaw tends to holdsaid clamp in folded posit-ion and also exerts suflicient pressure uponsaid clamp, when swung outward for engagement with a fixture, to fastenthe stand or lamp to said fixture whether applied to the edge of ahorizontal shelf or fixture'23, as shown in Figure 1, or applied in anyother position to any other kindof fixture, such as the bars of a metalbed, for instance, as will be readily understood. The clamp or jaw 20 ismade hook-shaped, as at 24, in order to better grip a fixture of angularor round contour, and said clamp is preferably made of rigid wire 25 orthe like bent into the form shown and covered or encased in rubbertubing 26, so that it will not mar the fixture to which it is applied.The base of the stand is fitted with a rubber encased wire 27 for thesame purpose.

The clamp 20 is operated from above the base of the lamp by means of ahand lever 28 which may be made of wire as shown in Figures 1, 2 and 3.,or which may be formed in a solid casting 29 as illustrated in Figure4-. Said wire lever 28 is bent to form oppositely extending loops 30which rest upon the top of the base of the lamp, while the middleportion of said wire is bent to form a handle loop 31, the end portions32 of the wire being spread apart to engage the hinged end of the'clamp20, while the portions 33 of said wire just below theloops 30 arearranged close together where they pass through an opening 34 in the topof the lamp base which serves as a ful rum for the lever. It will thusbe seen that the clamp 20 may be swung downward out of the recess in thelamp base by pressing upward on the handle loop 31, or outer end of thehandle lever 28, as shown in Figure 1, and that this outward movement ofthe clamp placed the spring 22 under suflicient tensionto clamp the lampfirmly upon a fixture to which it may be applied.

In Figure 4, the hand lever casting 29 has oppositely extending lugs 35corresponding to the loops 30 on the wire lever 28, and oppositelyextending arms 36 corresponding to the spread ends 32 of the wire leverfor engaging the hinged endof the clamp.

We claim:
